I don't know. I'm a bit disappointed. The ratings started out great today, but fell in a hole a bit towards the end of the day. I'm still posting too many races!!! I posted 18 races today and it really should have been no more than about 12-14. I recently went back over my results and worked out which types of races the ratings don't work so well on. And yet today, I still fell into the trap of posting some of those races. It's no surprise that the ratings weren't successful in any of them.
